Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] Embodiments of the invention include:

[0020] A casting casting process method, comprising the steps of:

[0021] Step 1. Coating configuration. The coating configuration includes the following components: sodium silicate, talcum powder, zinc oxide, kaolin, graphite and warm water. The above components are mixed and configured according to a certain ratio;

[0022] Step 2. Fully stir the prepared paint, filter it with a 450-mesh screen after stirring evenly, and then put the filtered paint into the spray gun...

Abstract

The invention discloses a casting pouring process method. The casting pouring process method includes the following steps: (1) coating are prepared; (2) the prepared coatings are contained in a spraying gun for preparation; (3) pre-heating, coating spraying and cleaning are carried out on a die; (4) a casting ladle is cleaned, wherein oxide and sundries on the surface of the casting ladle are mainly cleaned; (5) the die is closed and firmly fastened; (6) casting molding is achieved. By means of the mode, the casting pouring process method has the advantages that cast castings are free of casting defects on the appearance, internal texture is relatively compact, the casting degree can be greatly improved, and the hardness of insides and outsides of the castings trends to be coincident; meanwhile, accidents can be effectively prevented from happening in the pouring process.

Description

[0001] technical field [0002] The invention relates to the field of mechanical casting, in particular to a casting casting process method. Background technique [0003] In the 20th century, the development of casting was very fast. One of the important factors was the progress of product technology, which required better mechanical and physical properties of castings while still having good machining performance; another reason was that the machinery industry itself and other The development of industries such as chemical industry and instrumentation has created favorable material conditions for the foundry industry. [0004] The size and weight of cast parts can be adapted to a wide range, and the metal types are almost unlimited; while the parts have general mechanical properties, they also have comprehensive properties such as wear resistance, corrosion resistance, and shock absorption. , welding, punching and so on can't be done. Therefore, in the machine manufacturi...
